Hi all - help please. I know nothing about windows and my T440s
is suffering from disk errors when sata link power management is
turned off an on (specifically, when plugging in ac after being on
battery).
I think this is a hardware fault. So I reinstalled windows 8 and need
to know how to control sata power to try to reproduce the problem
in windows.
I have the lenovo supplied 512gb ssd
But when I open the power control settings (advanced settings in power
options) there are no HIPM/DIPM settings under the hard drive tab.
Should I not see a "AHCI Link Power Management - HIPM/DIPM" setting?
I'm pretty lost here and any advice would be welcome.

answering myself, I found a registry change that reveals the HIPM/DIPM settings;
now, how do you tell what setting is active at any given time? -
further investigation turns up this in the output of powercfg -energy:
